Abstract
The invention provides an automatic balancing grit scraper which not only can uniformly stir a material in a grit chamber for quenching and tempering, but also can scrape and collect grit depositing at the bottom of the grit chamber into a groove in the bottom of the grit chamber. The automatic balancing grit scraper comprises a walking trolley 1, a working bridge 2, a scraper plate assembly cantilever support 3, a scraper plate assembly 4, a rotary support 5 and the like. The automatic balancing grit scraper has the most important advantages as follows: a driving motor is low in power, a scraper plate can overcome different resistance and can automatically balance for continuous operation under the action of a balancing weight without using any power, the walking trolley can also automatically balance on a rail with very poor flatness, a driving wheel is always positioned on the rail without dropping off, and the scraper plate assembly 4 is smooth and reliable in operation; therefore, the automatic balancing grit scraper is especially suitable for degritting in a closed toxic gas-containing grit chamber and degritting a material with high grit content.
Description
Technical field
Patent of the present invention is related to environmental protection facility field, proposes a kind of autobalance type sand scraper for the quenched desanding of large-scale setting pot.
Background technology
The treatment for cow manure of sewage disposal and a lot of plant generally will adopt setting pot desanding, and the method that setting pot desanding adopts at present has: sand discharge pumping sand, spiral sand removing machine or other sand removing machines remove sand, and sand scraper scrapes sand.Sand scraper substantially will be used if large-scale setting pot percent sand height.
Sand scraper is generally divided into center driving sand scraper and peripheral-traction bridge-type sand scraper.Center driving sand scraper is generally used for the setting pot desanding that internal diameter is less than 15 meters, and shortcoming is that motor power is big, is both inconvenient to keep in repair, is also inconvenient to operate in the setting pot containing toxic gas if in closing.Peripheral-traction bridge-type sand scraper is generally used for the setting pot desanding that internal diameter is more than 15 meters, efficiency high, and motor power is little, can carry out maintenance maintenance operation by driving reducing motor to rest at setting pot vent.
The sand scraper that the present invention provides belongs to one kind of peripheral-traction bridge-type sand scraper, and maximum feature is that fault rate is low, operates steadily, and treating capacity is big, is particularly suitable in the setting pot containing toxic gas of closing desanding and the high material desanding of percent sand.
Content of the invention
The invention provides a kind of can uniformly carry out modifier treatment by the material stirring in setting pot, the sand of setting pot bottom deposit can also be wiped off the autobalance type sand scraper being pooled in the groove of setting pot at the bottom of pond, the great advantage of this sand scraper is that motor power is little, scraper plate can overcome different resistances, without any power balancing weight effect under autobalance, continuous operation, walking dolly also can on the very poor track of flatness autobalance, all the time land will not step on sky to driving wheel in orbit, and scraper component 4 operates steadily reliability.
Autobalance type sand scraper is by walking dolly 1, service bridge 2, scraper component cantilever shalving 3, scraper component 4, revolving support 5 grade group prejudice Fig. 1.
Walking dolly 1 structure is shown in Fig. 2, by explosion-proof reducing motor 15, sprocket wheel chain gearing 18, drive wheel assemblies 16, driven pulley assembly 17, walking dolly support 10, plain bearing housing 9, sliding bearing 7, rotating shaft 8 grade forms, walking dolly support is made up of the middle connecting plate between 2 channel-section steels curving arc-shaped and channel-section steel, press-in sliding bearing 7 in two ends between rotating shaft 8 and plain bearing housing 9, plain bearing housing 9 is bolted on the axis of walking dolly support 10, explosion-proof reducing motor 15 and connected drive wheel assemblies 16, driven pulley assembly 17 is separately mounted in two outer end symmetric positions of the axis of walking dolly support 10, 10 liang of outer ends of walking dolly support can be swung up and down with rotating shaft 8 for axis.
Service bridge 2 is welded entirety using shaped steel, becomes u shape, and waffle slab is laid in u shape bottom, convenient operation maintainer operation.Service bridge 2 one end is positioned on the column of setting pot center by revolving support 5, and service bridge 2 other end connects walking dolly 1 by rotating shaft 8, and scraper component 4 is fixed on service bridge 2 by cantilever shalving 3
The attachment structure of walking dolly 1 and service bridge 2 is shown in Fig. 2, rotating shaft 8 two ends on walking dolly 1 are fixed on above service bridge gripper shoe 13, rotating shaft 8 two ends with locator card 14 spacing to above service bridge gripper shoe 13, avoid left and right vibration, also it is inserted in baffle ring 11 and wear-resisting baffle ring 12 between sliding bearing 7 and service bridge gripper shoe 13, reduce frictional force, this attachment structure makes the symmetrical drive wheel assemblies 16 in 10 liang of outer ends of walking dolly support, driven pulley assembly 17 can be swung up and down with rotating shaft 8 for axis, the axis of the axis of walking dolly support 10 and service bridge 2 is on one wire, the explosion-proof reducing motor 15 laid particular stress on and connected drive wheel assemblies 16 are pressed in setting pot track 19 all the time above without stepping on sky, scraper component 4 operates steadily reliability.
Scraper component cantilever shalving 3 is welded using shaped steel, cantilever shalving quantity is according to setting pot 6 internal diameter difference at 2 or more than 2, cantilever shalving upper end is bolted to service bridge and strengthens substrate, and cantilever shalving is middle and lower end one root type material connects into an entirety, forms scraper plate connecting seat.Bottom scraper plate connecting seat is welded with multigroup free bearing, and every group of free bearing joins a set of scraper component 4.
Scraper component 4 is by scraper plate 20, l shape swing arm 21, balancing weight 22, bearing pin 23, free bearing 24 forms, and l shape swing arm 21 one end steel of ining succession pours balancing weight 22, the other end is ined succession hard rubber scraper plate 20, l shape swing arm 21 can be around bearing pin 23 rotary oscillation, and bearing pin 23 passes through the location hole of l shape swing arm 21 to be fixed on free bearing 24, and free bearing 24 is fixed on cantilever shalving connecting seat 25.When service bridge 2 runs on setting pot peripheral rails around setting pot center column, scraper component is circumferentially run in setting pot 6 at the bottom of pond centered on the column of setting pot center also with service bridge, material in quenched stirring setting pot, the sand of at the bottom of pond is scraped in the groove be pooled to setting pot at the bottom of pond and transports on one side.
